Zoom, F3 was originally fitted with auto wing sweep, but problems during testing resulted in it being disabled. So yes it had, no it hasn't and it really wasn't that good. The reality is, that in any 'Tonka' the control of the wings is easy and is learnt within a few trips.
Really, it's a 3 position switch.... Foward for Slow, Mid for Fast Subsonic, Back for Very Fast Subsonic or Supersonic.
